Legal claims defining the scope of protection, as filed with the USPTO.
1. A method, comprising: defining a virtual space, wherein the virtual space comprises a plurality of first objects and a second object; defining a plurality of situations to be developed in the virtual space; associating each situation of the plurality of situations with a corresponding first object of the plurality of first objects; detecting motion by a user associated with a head-mounted display (HMD); moving the second object in accordance with the detected motion; selecting a first object of the plurality of first objects using the second object; updating the virtual space to a virtual space corresponding to a situation of the plurality of situations corresponding to the selected first object; displaying in the virtual space a plurality of words associated with the corresponding situation; selecting at least one word of the plurality of words based on the detected motion; and associating the selected at least one word with the selected situation and registering the associated at least one word in a word list.
2. The method according to claim 1 , further comprising displaying in the virtual space a word registered in the word list.
3. The method according to claim 1 , further comprising: identifying, from the plurality of situations, a situation associated with the at least one word registered in the word list; updating the virtual space to the identified situation; and presenting in the updated virtual space the word associated with the situation in the word list.
4. The method according to claim 1 , further comprising: associating each word of the plurality of words with a corresponding third object of a plurality of third objects in the virtual space; selecting a third object of the plurality of third objects using the second object; and selecting a word of the plurality of words corresponding to the selected third object.
5. The method according to claim 1 , further comprising: selecting a first object of the plurality of first objects based on a detected line of sight of the user; and identifying a word of the plurality of words corresponding to the selected first object.
6. The method according to claim 1 , further comprising: receiving a command by a second user, the command comprising information for designating the plurality of words; and presenting in the updated virtual space, among the plurality of words associated with the situation, the plurality of words designated in accordance with the command.
7. The method according to claim 1 , wherein the plurality of words comprise at least one word that satisfies an answer criterion determined in advance and at least one word that fails to satisfy the answer criterion.
8. The method according to claim 1 , further comprising: displaying on the HMD an example sentence associated with the plurality of words; displaying a first word of the plurality of words that satisfies the answer criterion for the example sentence; displaying a second word of the plurality of words that fails to satisfy the answer criterion; and displaying a hint for the example sentence.
9. The method according to claim 8 , wherein the displaying of the hint comprises displaying the hint in accordance with an instruction from the user.
10. The method according to claim 8 , wherein the displaying of the hint comprises displaying the hint in accordance with an operation by a second user.
11. The method according to claim 8 , further comprising presenting the hint on the HMD in response to a failure to select the at least one word satisfying the answer criterion within a period of time selected in advance.
12. A system, comprising: a head-mounted display (HMD); a processor; and a non-transitory computer readable medium connected to the processor, wherein the non-transitory computer readable medium is configured to store a program, and the processor is configured to execute the program for: defining a virtual space, wherein the virtual space comprises a plurality of first objects and a second object; receiving a plurality of situations to be developed in the virtual space; associating each situation of the plurality of situations with a corresponding first object of the plurality of first objects; detecting motion by a user associated with the HMD; moving the second object in accordance with the detected motion; selecting a first object of the plurality of first objects using the second object; updating the virtual space to a virtual space corresponding to a situation of the plurality of situations corresponding to the selected first object; instructing the HMD to display, in the virtual space, a plurality of words associated with the corresponding situation; selecting at least one word of the plurality of words based on the detected motion; and associating the selected at least one word with the selected situation and registering the associated at least one word in a word list.
13. The system according to claim 12 , wherein the processor is further configured to instruct the HMD to display, in the virtual space, a word registered in the word list.
14. The system according to claim 12 , wherein the processor is further configured to execute the program for: identifying, from the plurality of situations, a situation associated with the at least one word registered in the word list; updating the virtual space to the identified situation; and instructing the HMD to display, in the updated virtual space, the word associated with the situation in the word list.
15. The system according to claim 12 , wherein the processor is further configured to execute the program for: associating each word of the plurality of words with a corresponding third object of a plurality of third objects in the virtual space; selecting a third object of the plurality of third objects using the second object; and selecting a word of the plurality of words corresponding to the selected third object.
16. The system according to claim 12 , wherein the processor is further configured to execute the program for: selecting a first object of the plurality of first objects based on a detected line of sight of the user; and identifying a word of the plurality of words corresponding to the selected first object.
17. The system according to claim 12 , wherein the processor is further configured to execute the program for: receiving a command from a second user, the command comprising information for designating the plurality of words; and instructing the HMD to display, in the updated virtual space, among the plurality of words associated with the situation, the plurality of words designated in accordance with the command.
18. The system according to claim 12 , wherein the plurality of words comprise at least one word that satisfies an answer criterion determined in advance and at least one word that fails to satisfy the answer criterion.
19. The method according to claim 12 , wherein the processor is further configured to execute the program for: instructing the HMD to display an example sentence associated with the plurality of words; instructing the HMD to display a first word of the plurality of words that satisfies the answer criterion for the example sentence; instructing the HMD to display a second word of the plurality of words that fails to satisfy the answer criterion; and instructing the HMD to display a hint for the example sentence.
20. The system according to claim 19 , wherein the processor is further configured to execute the program for instructing the HMD to display the hint in response to a failure to select the at least one word satisfying the answer criterion within a period of time selected in advance.
